To provide an on-water basket ball goal used for a basket ball game played on water.

The on-water basket ball goal 1 is composed of an annular goal ring 2, cylindrical poles, a floating part 4 and a connector. In the annular goal ring 2, a hole is formed at a center of inside to form an outer slope 2a inclined at an acute angle from the outer peripheral surface of an upper surface toward the hole and an inner slope 2b inclined gently from the inner periphery of the outer slope 2a toward the hole; three connection holes are formed at a bottom surface in a positional relation of apexes of a regular triangle; and a net is fitted. The cylindrical poles are put through the respective connection holes. In the floating part 4 composed of a base main body, a recess part is formed in its center; a gently expanding curved part is formed at a bottom surface; three connection holes through which the lower parts of the poles are put in a positional relation of the regular triangle and where drain holes are formed in the center of a lower surface are formed at an upper surface; and a side face is widened downward. In the connector, suckers each provided with a projecting part having an L-shaped hole formed therethrough from an upper surface to a side surface at an upper surface in the center are fitted to both of the ends of a connection member having two or more holes formed at both of its end. Then, one of the suckers is made to suck the floating part, and the other is made to suck the wall etc. of a swimming pool.
